Review: Works for a 2005 prius stolen catalytic converter - Someone stole my catalytic converter by sawing it off of the resonator, and this catalytic converter worked great to get my 2005 prius back up and running. If you recover the bolts with springs, you will only need to purchase some exhaust clamps (1.75 inch from autozone for a few bucks, SureBilt 1 3/4in 17122) to finish the install. I took it a step further and used muffler sealer (permatex 80335) to seal the joint. If you dont have both bolts and their springs (like me), you can buy the replacements. I used Dorman 675-221 and they worked great. This catalytic converter comes with just the catalytic converter and a coupler. The coupler is perfectly sized to slide over the catalytic pipe and your remaining resonator pipe. You will need a long extension to get the screws through the cat into the engine. I used a 10" and a 4". Parts needed: This catalytic converter Bolts with springs (if you could not recover them). Dorman 675-221 Oxygen sensor (I suggest denso) Two 1 3/4 exhaust clamps (autozone Surebilt 17122) Permatex muffler sealer 80335 Install instructions (according to how I did it): Before install, consider engraving your license plate onto the cats and painting the cats red to irritate future thieves. 1. Clean up the resonator pipe and smooth it out so that the coupler can fit on the resonator. I used a dremel cutting wheel to cut off the jagged pieces and then the sanding attachment to smooth it out. 2. Rough up the surfaces of the coupler and pipes where the muffler sealer will be so it sticks well. I used a dremel sanding attachment. 2. Put the coupler on the catalytic pipe and hold it while you push the cat against the engine exhaust. 3. With the cat pipe and the resonator pipe touching, slide the coupler over the mounting area to test fit. 4. The pressure from the engine and the exhaust should now temporarily hold the cat in place. 5. Try to thread the bolts through the catalytic converter into the engine mount. This is the hardest step. The springs will fight you the entire time you try to get the threads to grab. I used an electric drill/driver to spin while I provided gentle, but steady force and it worked well. Dont screw it all the way in yet. 6. Slide the coupler of the joint (onto the cat pipe) and slather the muffler sealer all over the surface where the couple will go. 7. Slide the coupler back over the joint between the cat and resonator. 8. Mount the two exhaust clamps (one over the cat side of the join, and the other over the resonator side). 9. Tighten the cat bolts to 32 ft/lbs of torque. 10. Drive the prius on the highway for at least 30 min to set the muffler sealer. Review: Compatible with 2007 Toyota Prius - Walker 16337 is installed in 2007 Prius. That worked for me. It disappeared p0420 code and get 10% increased mpg . That is great catalytic converter . I liked it. ## Features - COMPATIBILITY – Fits 2004-2009 Toyota Prius - GET THE RIGHT PART -- Before purchasing, please check the “desertcart Confirmed Fit” bar to ensure this part will fit your vehicle; enter all vehicle information (year, make, model, engine and trim) for compatibility and check qualifier notes.
